错误信息：

Undefined symbols for architecture armv7s: "_GCControllerDidDisconnectNotification", referenced from: -[GCControllerConnectionEventHandler observerConnection:disconnection:] in libcocos2dx iOS.a(CCController-iOS.o) "_GCControllerDidConnectNotification",0)">"_OBJC_CLASS_$_MPMoviePlayerController", referenced from: objc-class-ref in libcocos2dx iOS.a(UIVideoPlayerIOS.o) "_OBJC_CLASS_$_GCController",175)">CCController-iOS.o) (maybe you meant: _OBJC_CLASS_$_GCControllerConnectionEventHandler)

这个找了一下，貌似忘记了添加一个GameController.framework，添加这个framework之后就没有这个问题了。但是当在低版本的iOS6上面运行的时候，总是提示"dyld: Library not loaded: /System/Library/Frameworks/GameController.framewor"，这个问题的修改方式是把GameController.framework勾选为"Optional"即可
